Ball Lock Liquid Disconnect with Swivel Nut and Worm Clamp for Corny Keg Home Brewing and Wine Making by PERA

Good price.

The CarbaCap was specifically designed for the GRAY gas injector and not for the BLACK liquid coupler.You won't find that out until you get this and it doesn't fit. I had to contact CarbaCap to get this information.

Works great, doesn’t leak. Pricy compared to the local brew shop, but not when you include the price of fuel...
